Basalt Cave is a Coconino National Forest lava tube — a small entrance that opens into a large chamber with approximately 700ft of walking passage, 20ft ceilings, and 30ft+ width. The slippery, muddy floor indicates the cave is still active. Active scientific data loggers were present — do not touch them. A marked trail minimizes floor impact.

Impressive — it kept going further than expected. The Coconino has numerous lava tube caves ranging from small rooms to passages exceeding a mile in length. Contact your local grotto for information on responsible visits.
